Natural light! Thank you, water damage.
Darren, Seb and I had access to shoot the interior of this school. Unfortunately, the owners had every window boarded tight a few months earlier. This resulted in horrible mold growth, and almost no light in any of the rooms. I own a cheap flash, but I almost never use it - especially while shooting urbex.
I was not really prepared to shoot in total darkness and I'm not happy with almost any of the shots from this day - this one I like because it had some decent light! But, I learned a lot, and hopefully I'll do better with the next pitch-black location. (plus I'll have better gear by then ;)
